class='rss_texte'><p>At the inauguration of the <a href='https://mathemarium.fr/Inauguration-de-la-bibliotheque-Jean.html'>Jean Céa Library</a>, LJAD presented a preliminary version of its <a href='https://mathemarium.fr/-Mathotheque-.html'>Mathothèque</a> , a system for lending mathematical objects to LJAD members for their conferences, courses, and scientific outreach activities.</p> <p>The library contains 32 objects and devices (out of more than 100 in the Mathemarium), ranging from the most classic to the most original, all made in the Mathemarium's <a href='https://mathemarium.fr/-Mamath-Makerspace-pour-les-Maths-.html'>makerspace</a>.</p> <p>No fewer than 21 people participated in the design and manufacture of the objects available in the Mathothèque, mainly from the laboratory, but also students and doctoral students in mathematics, participants in fabrikathons, a colleague from INRAe, colleagues from Kit Math CNRS, and... middle school students on a 9<sup class="typo_exposants">th</sup> grade internship.</p> <p>All around are illustrations from a flipbook created by Indira Chatterji, showing a homotopy (= continuous deformation) of a Klein bottle from which a disc has been removed (allowing us to immerse it in space), and Moebius's slip.</p> <p>The project and design were carried out by <a
